leading to a fine tuning of \(\Delta _{\textrm {FT},n=1}\)  of \(\sim 5\%\)  for both benchmarks. The lower \(\Lambda _y\)  in BM2 is partly compensated by the higher top Yukawa \(y_t(p=0)\) . In the case of a composite top quark consisting of \(n\)  constituent preons, the more general formula (REF ) for \(n>1\)  would hold [1]} and could lead to a drastic reduction in fine tuning.
